Pictures are of a 61 year old woman with residual fatty tissue, and thickening of the skin between the eyebrows100% strength TCA was applied with a Q-tip, and left on 1 hour (remember this person had tough skin with fat beneath the area).The skin burned, and scabbed over. The yellow layer could be seen at that point because the burn was very deep, and healing took a full month. The end result, flat skin, smaller pores, and a better lookI do not recommend doing this without a doctors assistence
